It measures 0.125 inches in diameter with a 0.5 inch length of cut and a 1.5 inch overall length. Constructed from solid carbide micrograin substrate, it carries a TiCN (titanium carbonitride) finish that extends tool life in moderate- to high-speed applications. The 4-flute, 30-degree helix spiral configuration promotes efficient chip evacuation while maintaining a quality surface finish. Centercutting geometry allows for direct plunge entry. This tool is installed by machinists and CNC tooling technicians working in job shops, production facilities, and maintenance machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and contouring operations on a variety of workpiece materials. The 0.125 inch shank diameter matches standard collet and toolholder sizes common to CNC machining centers and manual mills. The regular length designation makes it appropriate for general-purpose applications where extended reach is not required. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling setups on most machine platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.125 inch cutting diameter with micrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides improved hardness and lubricity compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003e4-flute, 30-degree spiral helix balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard CNC and manual mill setups\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.001 inches ensures consistent fitment in tight-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 0.125 inch collets and toolholders on CNC machining centers, knee mills, and similar milling equipment.

The machine spindle must be fully stopped and the machine placed in an energy-isolated state before changing tooling. Use a calibrated torque wrench and the appropriate collet nut spanner when seating the shank in the collet to avoid over-tightening or runout. Inspect the cutting edges and shank for chips or surface damage before mounting; carbide tooling is brittle and should not be used if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 404-125008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732496351538,"sku":"404-125008","price":25.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/292e1e5c9fefb6d10c3f0750e71c4898.jpg?v=1788743593","url":"https:\/\/voomisupply.com\/products\/osg-404-125008-square-end-mill-0-125-in-4-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
